A900 Rocket Food Waste Composter

Food waste solutions for larger scale sites

The A900 is the most widely used machine in our collection – often implemented by large-scale hotels, universities, and remote islands across the globe.

The Composter can process up to 215 litres of food waste per day but has only one moving part and incredibly low running and maintenance requirements.

Helping businesses, education and hospitality establishments across the world to recover the resource potential from their food waste, our A900 Rocket model is a composting tool celebrated by many users worldwide.

  • Spec Sheet

With its 215-litre daily processing capacity, it’s an ideal choice for larger organisations or those with multiple sites or campuses, looking for a long-term food waste recycling solution.

As well as creating a nutrient-rich compost resource in just 14 days, the A900 is also a key player in helping sites to improve their carbon footprint – reducing the number of off-site disposal trucks or eliminating them entirely.

It is designed to easily process a range of organic wastes, such as cooked and uncooked meat, fish, fruit and vegetables, alongside garden and animal waste (including some types of bedding).


This particular in-vessel composter is used by many brands such as South Lodge Hotel, City of Glasgow College, Bank of America, HM Prison Service and British Petroleum – to name a few.

You can increase your overall capacity by first processing food waste with our Dehydra Dewaterer. This equipment chops up and removes liquids first, before feeding it into the composter, to significantly increase the overall throughput (see below).

Alternatively, it can also form part of a fully containerised system in our Comptainer – a space which allows two composting units to be housed side by side.










Up to 215 litres of food waste per day*
*This is determined by the feed materials used, loading frequency and operating conditions. Please get in touch if you need any advice on how to achieve maximum throughput.
